Model uncertainties

Models are by definition affected by uncertainties (in input data, input parameters, scenario definitions, etc.). Have the model uncertainties been quantified? Are uncertainties accounted for in your simulations?

yes
TRUST assigns O/D matrices at NUTS3 level. Intra-zonal traffic is not assigned on the network, although it is taken into account as pre-load on road links. The lack of intra-zonal demand modelling might be particularly relevant for passenger demand as the most part of it is short to medium distance. TRUST rail assignment does not consider capacity restrictions. This means that transport volumes on the rail links are computed irrespective of the availability of rail services and of transport chains. Given the strategic European scale of the model, detailed analysis at local level or at project level are outside its scope.

    Sensitivity analysis

    Sensitivity analysis helps identifying the uncertain inputs mostly responsible for the uncertainty in the model responses. Has the model undergone sensitivity analysis?

    yes
    Sensitivity analysis on key model’s parameters are regularly performed during the calibration of the model and its applications.

      Have model results been published in peer-reviewed articles?

      no

        Has the model formally undergone scientific review by a panel of international experts?

        Please note that this does not refer to the cases when model results were validated by stakeholders.

        no

          Model validation

          Has model validation been done? Have model predictions been confronted with observed data (ex-post)?

          no

            Transparency

            To what extent do input data come from publicly available sources?

            This may include sources accessible upon subscription and/or payment

            Based on both publicly available and restricted-access sources

            Is the full model database as such available to external users?

            Whether or not it implies a specific procedure or a fee

            no
            TRUST model databases are the results of TRT work of harmonization and integration of different sources, including public ones.

              Have model results been presented in publicly available reports?

              Note this excludes IA reports.

              yes

              Have output datasets been made publicly available?

              Note this could also imply a specific procedure or a fee.

              no
              Results of model applications are provided to the Client. The Client has the right to make outputs publicly available or not.

                Is there any user friendly interface presenting model results that is accessible to the public?

                For instance: Dashboard, interactive interfaces...

                no

                  Has the model been documented in a publicly available dedicated report or a manual?

                  Note this excludes IA reports.

                  yes

                  Is there a dedicated public website where information about the model is provided?

                  yes

                  Is the model code open-source?

                  no

                  Can the code be accessed upon request?

                  no
